first thing, idont usually change my lane unless i cant farm under tower range if you cant farm like this first tell your jungle to camp mid if that doesnt work ill swich lanes, in solo queue an smart team will let you change lanes.
as for the meta 1,1,1,2, if you know how your team comp works you can came with crazy things on lanes like bot AP nidalee and soraka(for crazy domination) with an AD caster on top and a supportive jungler like maokay/urdyr hit harder in the minds of the enemy team just have to be creative and SMART at time when you team is about to pick.
another thing if you are lossing your lane and die and die, actually if you are farming is a good think (sound weird but is real) after you top, or bot take down his tower you can go there and push like mad bait 1,2 people and split them since you dont worth be killed at that point (your death will be paided for 20g if you die 7times or more in a row ) is important to dont make kills but ass much assist as you can to get gold but not lose your death streak cuz that make you a treat for you enemy team contantly spliting them. if they dont come for you you will take 1-2 tower in the way and you are getting again in the game for constant farm.
please people learn to use you brain is a game of strategy not brute force..!
